Specification of Letters Patent.

Patented Jan. 14, 1913.

Application filed May 2, 1912. Serial No. 694,729.

To all whom it may concern:

Be it known that 1, CHARLES ALBERT Boo'rrr, a citizen of the United States, residing at Brunswick, in the county of Fred erick and State of ll laryland, have invented certain new and useful Improvements in Valve Construction; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

My invention relates to new and useful improvements in valve construction and more particularly to that class adapted to be used in connection with water tanks employed for supplying water to boilers or the like and my object is to provide a valve and place the same in communication with the pipe leading from the tank to the boiler.

A further object is to construct the valve in two sections and provide means for positioning the sections against the face of the valve casing so that any wear upon the edges of the valve will be automatically compensated for.

A further object is to provide perforations transversely through the valve, thereby providing a screen for the water passing through the valve to remove foreign particles therefrom, and, a further object is to provide means for rotating the valve in its casing, whereby the valve may be so adjusted as to entirely close the passage through the pipe or position the valve so that the sediment collected thereby will be flushed from the casing through a waste ort.

Other objects and advantages will be hereinafter set forth and pointed out in the following specification.

In the accompanying drawings which are made a part of this application, Figure 1 is a transverse sectional view through the valve, pipes connected thereto and a portion of a tank. Fig. 2 is a longitudinal sectional view through the valve, and, Fig. 3 is a top plan view of a segmental rack for controlling the position of the valve in its casing.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates a section of a tank such as is commonly used upon tenders for railway locomotives and 2 indicates an outlet pipe employed for conveying the water from the tank to the boiler (not shown). Located in the wall of the casing at all times.

the length of the pipe 2 is a casing 3 in which is located my improved form of valve l, saidvalve being preferably constructed in two sections 5 and 6, the inner edges of said sections having registering sockets 7 and 8, respectively, through which extends a key 9. The edges of the key are preferably tapered longitudinally as are also the openings in the sockets 7 and 8 and by making the openings in the sockets slightly greater in extent than the width of the key, the inward lengthwise movement of said key will move the sections of the valve outwardly and keep them in proper juxtaposition to The inner end of the key is preferably provided with a pintle 10 which enters a socket 11 in one end of the casing 3, while the opposite end of the key is provided with a shank 12 -which projects through the opposite end of the valve casing and by placing a spring 13 around the shank and between the end of the key and the wall of the end section of the casing, constant inward pressure will be directed against the key, thus automatically adjusting the valve in relation to the wall of the casing.

Any suitable means may be employed for rotating the valve 4:, but for the purpose of illustrating the operation thereof I have shown the outer end of the shank 12 provided with a bevel gear 14 with which meshes a similar gear 15 attached to the lower end of a shaft 16 which shaft extends upwardly to the upper edge of the tank and is provided with a spring latch 17 which in turn cooperates with a segmental rack 18. The rack is provided preferably with three notches 19, 20 and 21, which notches regulate the position of the valve within its casmg.

Then the latch 17 is engaged with the notch 19 the valve is in the position shown by full lines in Fig. 1 and when shifted to a position to engage the notch 21 the valve will be in the position shown by dotted lines in Fig. 1, the outer edges of the valve being then positioned over the openings 22 and 23 communicating with the casing of the valve, thus completely stopping the flow of the water from the tank.

. The valve 4: is provided with a plurality of perforations 24: through which the water passes from the tank and by providing said openings the valve is converted into a screen and serves to remove from the water any cinders or other foreign particles contained within the tank and delivers the water to the injector or pump on the boiler in a more or less purified state. After a certain amount of the foreign particles have been gathered within the casing, the latch 17 is moved into engagement with the notch 20, thus turning the valve to a position midway between that shown by the full and dotted lines in Fig. 1, thus uncovering a discharge port 25 in the lower portion of the valve casing and at the same time placing the valve at such an angle that the water entering the casing through the opening 22 will flush any foreign particles contained in the casing out through the discharge port 25. As soon as the valve and easing have been thoroughly cleansed the latch is again moved into engagement with the notch 19, thus placing the valve in vertical position, the lower edge thereof completely closing the port 25, while the opening 24 will be in direct alinement with the travel of the water through the pipe 2.

In operation, when the valve is turned to the position shown in full lines in Fig. 1, the water will pass'direct from the tank through the openings in the valve and through a pipe or hose 26 to the injector or pump of the boiler. It frequently happens that foreign particles are contained in the water so that the injectors and valves cooperating therewith become clogged and inoperative and in overcoming this objectionable feature various forms of screens have been used which require the removal of the screens from their casings in order to free them of the foreign particles gathered thereon and this work is required to be done when the engine is standing still, but in this instance the foreign particles can be removed from the water and the sediment thus collected removed from the valve while the engine is in motion. It also frequently happens that the hose connecting the tank with the engine becomes perforated or disconnected and permits the water to escape from the tank until such time as the flow of water can be stopped by supplying a new hose or operating a valve by hand, thus permitting the escape of a considerable amount of water, while by using my improved valve the flow of the water from the tank can be instantly stopped, thus preventing e aste of the water resulting from the burstin or disconnecting of the pipe. It will further be seen that by forming the valve in two sections and mounting the same upon a spring pressed tapered key that the outer edges of the valve sections will be held firmly seated against the wall of the casing and any wear upon the valve compensated for. It will likewise be seen that by providing the controlling means as shown or any other suitable controlling means that the valve can be instantly turned to the various positions and held in said position by the engagement of the spring latch with the notches in the segmental *ack.

This valve can be very cheaply constructed and readily applied to use and, although I have described the same as particularly adaptable for use in connection with railway locomotives, it can be used in connection with any tank and injector.

\Vhat I claim is 1. A valve construction comprising a casing having ports therein for the passage of water and a discharge port, a two part perforate valve within the casing, a spring pressed tapered key controlling the valve sections, means to rotate said valve to cause the water to pass through one of said ports and the discharge port or stop the flow of water through the casing and means to hold the valve in various adjusted positions.

2. A valve construction comprising a casing, a valve formed in sections, the meeting edges of which are provided with alining sockets, said sections having perforations therethrough, a tapered key extending through said sockets and means to direct pressure against one end of said key.

8. A va ve construction comprising the combination with a casing, of a perforate valve formed in two sections, the meeting edges of said sections having alining sockets, a tapered key extending through said sockets, means to rotate the valve within the casing and additional means to hold said valve in various positions.

4. A valve construction comprising a casing, a valve formed in two sections and having perfo ations therethrough and means to hold said sections in cooperation with each other and properly seated against the wall of the casing.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
